Title: Improvements in and relating to a fuel element for nuclear reactors
Inventor: DELPEYROUX PAUL
IPC: G21C3/04
Filed: 1963-06-21
Abstract: 963,877. Fuel elements. COMMISSARIAT A L'ENERGIE ATOMIQUE. June 21, 1963 [June 22, 1962], No. 24754/63. Heading G6C. Ratchetting in any direction is prevented in a sheathed nuclear fuel rod by forming at least two grooves extending in different directions in the surface of the rod which is in contact with the sheath, the groove depth and sheath thickness being such that the exterior sheath surface is corrugated when the cam is pressed into the grooves. The fuel rod (fissile or fertile) is preferably pure or alloyed uranium and may be in the form of a number of juxtaposed pellets. The sheath may be a magnesium alloy or stainless steel, and has its ends closed by welded caps 5 of like material. In the embodiment shown, the series of grooves is a pair of trapezoidal section grooves of equal and opposite helix angle, somewhat less than 45 degrees; this angle gives improved axial ratchetting protection at the expense of increased peripheral creep. The optimum angle is 45 degrees and it is preferable to have the ungrooved surface area of the rod approximately equal to the groove area. The fuel is coated by placing a plain tubular sheath over the grooved fuel, applying a preliminary fluid pressure of 100 kg/sq. cm. at room temperature, and then applying a final fluid pressure of 200 kg/sq. cm. at 400‹C.

Title: Control valves for hydraulically operated vehicle or other loaders
Inventor: MEATS WILLIAM HENRY
IPC: B66F9/04
Filed: 1951-10-24
Abstract: 712,424. Hydraulic load handling machines. TELEHOIST, Ltd. Aug. 11, 1952 [Oct. 24, 1951], No. 24831/51. Class 78 (3) A hydraulic ram for luffing a pivoted arm load handling device (not shown) has a rotary valve g for controlling the flow of fluid to the ram, a non-return ball valve u for preventing reverse movement of the ram and rotary valve lifting device v. When the valve g is in the shaded position, the pump p forces liquid from the reservoir r through pipes q, o, k and the non- return valve u into the cylinder and extends the rod f until a striker on the luffing arm (not shown), unlatches the'valve g and allows it to return under the action of a spring (not shown) into the unshaded position, whereupon the pressure set up in the cylinder by the force exerted on the rod by the load causes the valve u to close and thus the load is sustained. During this operation ,the valve lifter v; which is perforated to allow the liquid to pass, is in the position shown in which it does not engage the baLl of the valve u; but to effect lowering the lifter v is rotated through 90 degrees to lift the ball and allow the ram to exhaust through pipe m. If so desired the lifter v can be retained in this position to provide for automatic lowering as soon as the valve g is moved to its unshaded position. To render the ram inoperative the valve g is turned to a position closing the passage i whereupon the liquid circulates idly through pipes o, m, q. An automatic relief valve, comprising a spring loaded sleeve 4, is provided to uncover a port 3 and allow liquid to exhaust through passage 2 and pipe m if the sleeve is allowed to engage the right hand end of the cylinder.
